There are two musical situations on which I think we can be confident that a blessing rests. One is where a priest or an organist, himself a man of trained and delicate taste, humbly and charitable sacrifices his own (aesthetically right) desires and gives the people humbler and coarser fare than we would wish, in a belief (even, as it may be, the erroneous belief) that he can thus bring them to God. The other where the stupid and unmusical layman humbly and patiently, and above all silently, listens to music which he cannot, or cannot fully, appreciate, in the belief that it somehow glorifies God, and that if it does not edify him this must be his own defect. Neither such a High Brow nor such a Low Brow can be far out of the way. To both, Church Music will have been a means of grace; not the music they have liked, but the music they have disliked.

Lewis then goes on to point out the opposite situation results in pride, contempt and resentful hostility. A lot of churches have musical problems, and while I don't want to downplay the importance of a good music ministry, Lewis is helpful here in pointing out that the problem is not always a musical one. His situation is not completely analogous to today's, but so often our attitudes can be similar when we feel music is not done to our own personal taste or professionalism. I know I have been incredibly guilty of such a sin.
